Sais was an ancient Egyptian city in the Western Nile Delta on the Canopic branch of the Nile, known by the ancient Egyptians as Sꜣw. It was the provincial capital of Sap-Meh, the fifth nome of Lower Egypt and became the seat of power during the Twenty-fourth Dynasty of Egypt and the Saite Twenty-sixth Dynasty of Egypt during the Late Period. On its ruins today stands the town of Sa el-Hagar or Sa El Hajar.

The Nile Delta is the delta formed in Lower Egypt where the Nile River spreads out and drains into the Mediterranean Sea. It is one of the world's larger deltas—from Alexandria in the west to Port Said in the east, it covers 240 km (150 mi) of Mediterranean coastline and is a rich agricultural region. From north to south the delta is approximately 160 km (100 mi) in length. The Delta begins slightly down-river from Cairo.
